i CALL-REGISTERING MECHANISM.

Specification of Letters Patent. Patented June Y15, 1915.

Application lled December 14, 1912. Y Serial No. 736,878.

Mechanism, of whichthe following is a full,l

clear, concise, and exact description. This invention relates totelephone toll devices and more particularly to a device wherein toll iscollected andregistration is made for each successful call.

The object of this invention is to provide .a call registeringmechanismin combination with acoinv collecting apparatus-.which is simple inconstruction and eiiicient and reliable in operation.l To accomplishthis ob'- ject electromagnetically operated means un- 'Eder the controlof the coin distributing mechanism are provided whereby onlysuccejssfulcalls orv those forwhich a .coin 1s `collected are recorded by asuitable register-v ing'1 device. A This invention will be lfullyunderstood vfrom the following descriptiontakenvin connection with theaccompanying drawing in hic/hs Y Y Figure 1 is a side elevation, partlyin section, of a part of a coin collecting and registering deviceconstructed in accordance wit this invention; Fig. 2 is a side elevationof the coin collecting device with the inclosing housing and outer wallof the coin chute removed; Figs. 3 and 4 are detail views of the coindistributing mechanism showing the location yof the various elementsduring the 'depositing and refunding operations; and Fig. 5 is thepreferred system of "connections .shown dia'grammatically.

l A base plate 5 serves as the foundation for the coin distributingmechanism and registering device. Supported on the base plate 5 is azig-zag coin chute 6 of the usual ccnstruction provided withl coincollecting and coin returnA channels. An electromagnetic system composedof coils 7 and 8 is provided with a tilting armature 9 Aon which arelocatedtwofixed'pinsl() and 11 and a spring lpressed movable pin 12.`The pins carried by the armature project into the coin chute 6 above thedivergence of the deposit and refund channels and provide means forarrest;

ing aY vcoin in itsdownward course ,for clos'- irlg a breakin the signalcircuit and for directing the arrested coin` into either the deposit orrefund channel. The armature prise `a movable coin distributor which iskept in a central or neutral position by means of levers 13 and springs14C.

rrlhe registering mechanism or service meter lconsists of an actuatingcoil 15 con- Vtrollin a pivoted armature 16 to which is The pin 10 isinsulated'from the armaturev and is connected to an insulated contactpoint 25 on the pivotal axis thereof by an insulated conducting ,strip26; `Mounted upon the base or frame of the mechanism in any suitablemanner but insulated therefrom and from each other are two contactsprings 27 and 28. The contact spring 27 is provided-.with a contactpoint 29 adapted to be engaged by a pin 30 carried by armature 9 whenthe same is rotated in a counter clockwise direction, as shown. inFig,4, and is Y connected to one terminal of the coil 15 of the servicemeter by a conductor 31. The contactspring 28 1s provided with. acontact vand the pins carried thereby, therefore', com

32 engaging the contact point 25 when the p armature is in a neutralposition as shown in Fig. 5, but which is adapted to be removed thearmature; and a contact 33 adapted to vbe engaged by the armature whenthe saine is tilted in a clockwisev direction, as shown in Fig. Thespring 28 is Aconnecti-id one terminal of the-coil 7 of the 'coincollector magnet by means 'of aconductor 35i. Ene

' common terminal of coils 7 and 8 of the coin collector 'l distributing'magnet` is connected to coil 15 by conductor 35, while the independentterminal of coil 8 is-joined to the' line wire .L by a conductor.

When the armature is tilted f is @aber dii rection the contact betweenpoints 25 and 32 from such engagement upon the tilting of4 u is brokenon account-'of the spring 428 being raised slightly from its normalposition 1b?- f.

contacting with the edge of 'the 'armature' as shown in Fig. 3 or theinsulated buffer 37 as shown in F ig. Il. This contact is, however',lnot broken until the armature strikes the spring contact 28 or the pin30 vengages the contact 29 depending upon the `direction of movement ofthe armature.

A source of energy l0 furnishes the energizing current for operating thesystem through a pairof keys atl and 42.

In service a coin placed in the upper part of the chut-e6 and releasedis arrested between pins 11 and 12 as shown in Fig. 2. The movable pin12 contacts with the fixed pin 10 anda circuit is provided for thegrounded source of energy 4l() as follows: Line L, conductor 36, coils@and 7, conductor 34e, spring 28, contact points 32 and 25, conductingstrip 26, pins 10 and 12 to ground. Consequently, when either key il orl2 is closed current will flow over the circuit just traced. 1f the callis successful key 41, for example, is operated sending positive currentover the line to tilt the.

armature 9 in a counter-clockwise direction as shown in Fig. t. The coinis deposited breaking the contact' between pins l() and 12 and contactpoints -25 and 32. This breaking of the contacts, however, does not takeplace until the contact point 29 carried by spring 2'? has been engagedby pin 30 carried by the armature. A. circuit is, therefore, formed fromgrounded source of energy 40, line L, conductor 36, coil 8, con# ductor35, coil 15 of the service meter, conductor 31, spring 27, Contact point29, pin

30, armature 9 to ground. Current thus passes through the lservice metercoil which attracts its armature effecting the registration of the call.If, however, the call had been unsuccessful, current of the oppositepolarity would have been sent over the line to tilt the armature in a,clockwise direction as shown in F ig. 3. rEhe. coin is released into therefund channel and the contact ben tween pins lOand 12 is broken asliereinbefore described. This contact, however, is not broken untilcontact point 33 of the spring 28 engages with the armature 9. Currentthen passes fromgrounded source of energy d0, key ft2, line L, conductor36, coils 8 and 7, conductor 34, vspring 28, contact 33, armature 9 toground. 1t will thusl be observed fthat when a coin is returned nocurrent passes through coil 15 of the service. meter and no call isrecorded.

The coil 15 of the service meter being connected in a branch circuitwhich is substituted for one `winding of polarized magnet when the coindistributor is operated to collect a coin, may therefore beoperated fromthe same source of current as is used to operate the coincollectingmagnet and over a portion of the same circuit, thus greatly simplifyingthe Winding of the apparatus and avoiding` the use of a second source ofenergy for operating the register. Moreover, the actuating coil l5 willreceive substantially the same amount of current as is passed throughthe windings 7 and 8 when the coin distributor is operated. This resultsin a more positive operation of the register 13 than would be obtainedif the register was connected to operate from the coin distributer,sinceit is well known that a straight electromagnet will exert considerablygreater pull upon its armature in response to a given energizing currentthan will be exerted upon a centrally pivoted armature of a polarizedmagnet in response to the same amount of energizing current.
